“Catch the Wind” has been heard for years.
Today, its meaning is more poignant than ever.
Wind energy (wind power electricity and wind electricity) is low-cost and renewable, typically cheaper than oil, coal or natural gas, making it important in today’s economy and desire to rely less on foreign oil. The power of wind is undeniable. Through the use of turbines, we capture this power. Wind is the result of unequal temperatures on the earth’s surface. Turbines convert the kinetic energy in wind to power. The blades turn, a rotor harnesses the kinetic energy, and it’s converted to rotary motion and power that a generator disperses to power grids. By preventing further environmental damage, its fits today’s “Go green” philosophy
Today, wind has the capacity to light our homes, run transportation along railways, and provide virtually any other power for which we rely on electricity. Chances are, you’ve not seen the huge wind turbines in your communities just yet, but most of us have at least seen the pictures of them — acres and acres of gently-turning propellers covering the landscapes of open plains or ocean-side cliffs. The wind can produce energy that continues to flow — just like the wind itself.
Wind electricity is a growing area of interest especially given the concerns over global warming and the ill-effects of the fuel emissions we all breathe everyday. Carbon fuels, although effective, simply aren’t as clean and as sustainable as other sources such as wind. Already, wind provides over 80,000 cumulative megawatts of power and it’s projected to continue to grow over the coming years. Wind energy (and the resulting wind electricity) is low-cost and most importantly, renewable. It’s less expensive than oil, coal and most natural gas. The rippling effects of its use are more important today than ever as the economy and desire to rely less on foreign oil are forefront to most people.
We all have wind. It may be subtle and unnoticed at times when at others its force is unmistakable. The power of hurricanes and primarily the wind demonstrates the immense power it carries. When buildings and the earth itself are moved and transformed to images we no longer recognize, the power of wind is undeniable. Wind turbines capture this power. The technology behind it allows providers to harness it even when the wind appears to be calm to our eyes. Wind turbines can remain online and functioning, providing power to the nation’s power grids even through major disturbances. Wind farms can meet the expectations similar to those we put on thermal generators.
Today, with the use of electronics, the wind turbine’s blades can be adjusted to gain the best results. With the change of a blade’s pitch or angle, the turbines can continually run at optimum speed based on rotation and lift-to-drag of the blades. The result is the constant, maximum yield of energy possible. Even strong wind gusts can be absorbed and converted to electricity. How does it all work though? Wind is the result of unequal temperatures on the earth’s surface due to the sun. Wind turbines simply convert the kinetic (motion) energy in the wind to power (or electricity). When the wind spins the turbine’s blades, a rotor harnesses the kinetic energy in it and converts it to rotary motion that in turn powers a generator. The generators then disperse the power to grids and eventually our homes and cities.
Wind electrical systems are also available for the average consumer. Smaller, less expensive systems can be fit to your home or small business. You should take the time to thoroughly research it because it can be expensive, but the result can be worth it in the long run — both over traditional energy costs, but also in the satisfaction of preventing further environmental damage. “Going green” is definitely today’s buzz word and clean energy from wind electricity qualifies as a big contributor.
